If a freezer is humming unpleasantly loudly, there are usually reasons for this that you can easily eliminate. The humming usually comes from the compressor.
Freezer humming – causes and solutions
Freezers should be defrosted regularly. If you have not done this for a long time, it is advisable to empty the appliance completely and defrost.
- Similar to other electrical appliances, sufficient clearance should be maintained between the freezer and the rear wall as well as the freezer and side walls. Check that you are maintaining the safety distance specified in the operating instructions. If not, move the freezer a little away from the wall and measure with a folding rule.
- If the compressor constantly has to readjust the temperature, there is a good chance that the door is not closing properly and is letting air in. Check whether the seals are still elastic and tight.
- If you lower the temperature during the warm summer months, the freezer will need some time to reach the desired temperature. If the appliance hums during this time, everything is fine and the humming will stop as soon as the appliance has cooled down.
- Loose screws on the compressor can also be responsible, as can a vibration-induced humming due to uneven positioning. If you tighten the screws and reposition the freezer, the problem is usually solved.
- In addition, dust in the fan or defective bearings in the motor can cause the noise.
A vacuum cleaner can help with the first problem, while the second cause can only be remedied by having it repaired by the appropriate specialist personnel. - However, bear in mind that older appliances are often louder due to wear and tear and outdated technology. Place rubber mats under the freezer to dampen vibrations.
- A permanent humming without a cooling phase indicates a defective compressor which must be repaired immediately. This must be repaired immediately. This measure should be entrusted to a specialist company.
More tips against humming freezers
If you don’t hear a direct humming noise, but rather a rattling sound, objects in the freezer may be causing the noise.
- Check whether your appliance is in water, i.e. is standing upright. Most freezers have feet so that you can easily level out any unevenness in the floor. Use a spirit level to check.
- If the previous tips have not helped, other refrigerator parts such as the coolant or the electronics are probably to blame. In such cases, the only solution is to call customer service.
- Depending on the age of the appliance, you can make use of the warranty.
If you have an old fridge freezer, you should consider whether the electricity costs could justify a new one and rule out a repair. New appliances now only consume a fraction of the energy.
